...There is no universal action or sci fi or documentary.
I have to disagree. Comedy is very subjective. I'm British. I find very few American comedies funny. They have their moments, sure. But most of the time, I just don't get it.
Regardless of any language barrier, Action is still Action so long as people are shooting at each other and blowing shit up. Sci-Fi is still Sci-Fi so long as there's an alien or two (or three, or any one of the numerous other elements that make up the Sci-Fi genre). A Documentary is still a Documentary as long as it... well... documents something.
